Yep. Honeybucket is telling you the right stuff. People don't really think about it, but cell phones are radios and cell towers are pretty much like a linked repeater system. Those little radios just use the Cellular repeater system and when it goes down, so does those little radios. You are better off just operating your Bao Feng UV5R Handi-Talkie on FRS, MURS, or Marine band. If you aren't able to get enough distance out of that rubber duck antenna, you can always get an SMA to SO239 adapter for $3 and hook it up to an outside base station antenna. My daughter runs her Bao Feng UV5R Handi-Talkie in her car connected to a "Tram" Dual Band magnet mount mobile antenna and she can get about 10 miles range out of it using MURS.
